APPARATUS FOR SUPPLYING WATER OR OTHER LIQUIDS TO BRAKES.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed August 16,1906. Serial No. 330,815-

To all whom, it may concern:

Be it known that I, GIOVANNI ENRIoo, engineer, a subject of the King of Italy, residing at Turin, Oorso Dante 35, Italy, have invented certain new and useful Improvements in Apparatus for Supplying Water or other Liquid to Brakes, more especially intended for use with motor-vehicles, of which the following is a full, clear, and exact specification.

This invention has for its object to provide an arrangement whereby on the brakes being put on a jet of water or other liquid is thrown onto the bearing parts of the brake-shoes so as to prevent excessive heating and improve the efliciency of the brakes.

The accompanying drawing illustrates in longitudinal section an arrangement according to this invention.

1 is a lever actuating the brakes or con nected to any suitable part of the brake-operating mechanism. The lower end of the said lever 1 is provided with a finger 2, which when the lever comes near to its extreme position bears against a projection 3 on a rod 4, connected by a flexible piece 5 to the rod 6 of a piston 7, working in a cylinder 8 and terminating at its end 9 in a plug-valve for closing and opening a passage 10 for water or other liquid under pressure. The cylinder 8 is closed by a cover 11, which may be screwed into the cylinder, and within the cylinder is arranged a helical spring 12, one end of which presses on the piston 7, while the other end bears on the cover 11, so that the plug 9 is caused to normally close the passage 10. The cylinder 8 is provided with an outletnipple 13 for the attachment of a pipe running toward the brake-shoes.

hen the brakes are being put on, the lever 1 comes into the position shown in dotted lines in the drawing, and in this operation the rod 4 is momentarily brought to the position shown in dotted lines, so that the plugvalve 9 opens and permits water or other liquid under pressure to pass from the passage 10 into the pipe attached to the nipple 13 and thence to the brake-shoes. The admission of water or other liquid is merely momentary, for as soon as the lever 1 has been moved beyond the position shown in dotted lines the finger 2 becomes disengaged from the projection 3 and the rod 4, urged by the spring 12, returns to the position shown in full lines. When the lever 1 passes back from the position shown in dotted lines to that shown in full lines, the finger 2 in its rearward movement pushes the rod 4 downward, bending the flexible piece 5 against the action of a spring 14, which normally keeps the rod 4 in the position shown.

Having now particularly described and ascertained the nature of my said invention and in What manner the same is to be performed, I declare that what I claim is 1. For supplying water, or other liquid, to brakes especially those of motor-vehicles, the hereinbefore-described arrangement consisting in the provision on the brake-operating lever, or other suitable part, of a finger for bearing on a projection on a'va-lve-rod in such a manner that When the brakes are being put on a valve is opened so as to permit water, or other liquid, under pressure to pass to brake-shoes.

2. In a brake mechanism, a brake-operating lever, a valve operated by said lever, and a means for supplying liquid to a brake-shoe controlled by said valve.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
